Question

How many moles of CH4 are

in 64.2 g CH4?
64.2 g CH4
1 mol CH4
16.05 g CH4.

[?] moles CH4

Answer 1

To find the number of moles of CH4 in 64.2 g of methane, divide the mass by the molar mass of CH4 (16.05 g/mol), resulting in 4.0 moles.

Step-by-step explanation:

To calculate the number of moles of CH4 in 64.2 g, we use the molar mass of CH4 as the conversion factor. The molar mass of methane (CH4) is 16.05 g/mol. Therefore, we can set up the following equation:

Number of moles = mass (g) / molar mass (g/mol)
Number of moles of CH4 = 64.2 g / 16.05 g/mol

This calculation gives us:

Number of moles of CH4 = 4.0 moles

Therefore, there are 4.0 moles of CH4 in 64.2 grams of methane.
